Not detecting as a storage device

I am newbee to use BBB. I just went on through the getting started manual and booted the Angstrom. Later I followed the commnds given in BBB wiki and followed in ubuntu using terminal. Now I can’t find the LED’s blinking nor Drive in my computer when i connect to my PC.

Please any on help me.

LEDs do not blink on Ubuntu if I remember correctly.
